Occupant protection method and system, and computer readable medium

An occupant protection method executed by a processor configured to perform a series of steps, comprising:

• S1:
• collecting external environment information of a vehicle by using a radar and a camera;
• S2:
• determining, based on the environment information, whether there is an obstacle within a monitoring area of the vehicle;
• in response to the determination in step S2 that there is an obstacle within a monitoring area of the vehicle, proceeding to step S3;
• in response to the determination in step S2 that there is not an obstacle within a monitoring area of the vehicle, returning to step S1;
• S3:
• predicting a movement trajectory of the obstacle;
• S4:
• calculating a probability of collision between the vehicle and the obstacle based on vehicle body data of the vehicle, motion information of the vehicle, and the movement trajectory of the obstacle;
• S5:
• determining whether the probability of collision is greater than a collision threshold;
• in response to the determination in step S5 that the probability of collision is greater than a collision threshold, proceeding to step S6
• in response to the determination in step S5 that the probability of collision is not greater than a collision threshold, returning to step S1
• S6:
• partially inflating and deflating a seat cushion airbag of the vehicle to adjust a sitting posture of an occupant;
• S7:
• determining whether a collision is detected;
• In response to the determination in step S7 that a collision is detected, proceeding to step S8;
• In response to the determination in step S7 that a collision is not detected, returning to step S1;
• S8:
• fully inflating the seat cushion airbag to prevent the occupant from submarining.
